In real life, Marie de Guise was the second wife of King James V, and the mother of Mary Stuart (also known as Mary Queen of Scots) played by Adelaide Kane on the series.

Brenneman tweeted the following message:

"Reign" executive producer Brad Silberling is married to Brenneman and in the casting announcement Silberling said "Amy and Marie de Guise are a dream pairing of role and performer. Amy’s a huge fan of the show and the actors, and she can’t wait to come play.”

Laurie McCarthy, another executive producer on the series added "Amy’s character will face off with Megan Follows’ character (Catherine de Medici), not to mention her own daughter, Mary (Adelaide Kane). Hearts will break and blood will spill as a major battle of wits ensues.”

Aside from "Reign," Brenneman can also be seen in the upcoming HBO series, "The Leftovers."

"Reign" airs Thursdays at 9 p.m. EST on The CW.
